Import Deep Groove Ball Bearing — Buy in Bulk from Supplier in China

Deep groove ball bearings from Shanghai Shwin Bearings Co., Ltd. are precision-engineered components designed for radial and combined radial-axial load applications. The bearings are available in metric sizes ranging from 6 mm to 120 mm bore diameter, with standard series including 6000, 6200, and 6300, conforming to ISO 15 and DIN 625 standards. These units feature deep raceway grooves, steel cages, and sealed or open configurations depending on variant, enabling smooth rotation under moderate to high speeds.

The bearing components are manufactured from chrome steel GCr15, a standard material for industrial ball bearings due to its hardness and fatigue resistance. Typical internal clearance falls within the CN range, and surface finish of the races meets Ra 0.10 µm or better. Lubrication compatibility includes mineral oils and greases conforming to ISO 6743-4, with optional rubber seals offering basic dust and moisture protection. These are not ceramic or stainless variants; the product line focuses on standard carbon steel construction for cost-effective durability.

These bearings are commonly used in electric motors, gearboxes, conveyor drives, and agricultural machinery where continuous operation and low noise are critical. Buyers include OEMs in the automotive sector, maintenance contractors in manufacturing plants, and distributors supplying industrial repair markets. Trade terms offered include FOB Shanghai and CIF ports, with packaging in single-piece corrugated boxes or bulk cartons of 100 to 500 units. Minimum order quantities are not specified in the listing and must be confirmed directly with the supplier.
